More evidence

Today an article in Archives of Internal Medicine on the benefits of a low carb diet with a vegetarian twist.

It benefitted blood pressure, apolipoproteins and the ratio between total and ldl cholesterol.

More proof that carbs are not good for us.

I've been looking at articles from as far back as 2000, regarding things like "the metabolic syndrome, LDL particle size, and atheroclerosis: the Atherosclerosis and Insulin Resistance
(AIR) study". This was the first study to show a relationship between having small LDL particle size, metabolic syndrome and thickening of plaques in the arterial walls carotid and femoral arteries. And smaller LDL particles are not good.

Another article from the Arteriosclerosis, Thrombosis and Vascular Biology journal, called "Change in LDL particle size is associated with change in plasma triglyceride concentration", talks about how LDL particle size is inversely related to plasma triglyceride concentrations, so the higher your triglycerides, the smaller the size of your LDL particles. It seems the smaller particles are the ones found in plaque folks.

I'm painting a picture here.

So how to lower your plasma triglycerides? Eat fewer carbs. In Canada the RDA for carbs is about 300 g. On South Beach, I would say you get less than 20g a day during Phase I, probably 50 during phase II and less than 100g during Phase III and the rest of your life, depending on whether you gain weight or not.

Exercise is also good for you. It burns whatever glucose you might have in your system and gets you into fat burning mode. It also increases your fitness level and endurance.

Gary Taubes explains it so well

Watched his lecture at Berkeley again.

At the hour point, he cuts to the chase. Fat storage happens because of alpha glycerol phosphate, which is needed to bin fatty acids into triglycerides. AGP (my abbrev.) comes from burning glucose and nore is available to store fat when insulin levels are high. Want to store less fat? Keep insulin levels in the blood low. Take in less glucose.

Yalow and Berson in 1965 say "Insulin is the principal regulator of fat metabolism". Gary talks about how emaciated type I diabetics can be, as they no longer produce their own insulin. They have nothing to drive fat accumulation with. When treated with insulin therapy, Dr. Best (yes, that Dr. Best) describes how they develop adipose deposits in the stomach where the insulin is injected.

My husband and I started the South Beach Diet in late September 08. My husband has lost 25 pounds and his blood profile has improved so much his doctor is ecstatic. My husband's triglycerides are WAY down from where they were. The doctor had recommended South Beach. I have lost 17 pounds. Don't you hate men who always win in the weight loss game? My profile is improving as well. LDL and HDL levels close to normal.

It's the insulin, stupid.
